Description:

IBPP, where 'PP' stands for '++', is a C++ client interface for
Firebird Server versions 1.0, 1.5 and further. It also works with
InterBase(r) 6.0, though it is expected it might only support Firebird
in the future. It is a class library, free of any specific development
tool dependancies. It is not tied to any 'visual' or 'RAD' tool. It
was indeed developed to add Firebird access in any C++ application.
Those applications using IBPP can be non-visual (CORBA/COM objects,
other libraries of classes and functions, procedural 'legacy' code,
for instance). But it can of course also be used in visual or RAD
environments. IBPP is indeed purely a dynamic SQL interface to
Firebird. In some easy to use C++ classes, you will find nearly all
what is needed to access a Firebird database, and manipulate the data.
IBPP also offers access to most of the administrations tasks :
creating a database, modifying its structure, performing online
backups, administering user accounts on the server and so on.
